1. "It's never let a woman down."

Seriously? Really? You're gonna use a line that your grandfather inherited from his grandfather's grandfather? If you attempt to employ the most common and blatant man-lie told since the beginning of time, be prepared to wake up alone. No man on earth has a perfect track record, and every lady knows it. Hell, even George Clooney has disappointed a woman. In fact, the vast majority of us usually fail to “finish the job” because she's got so many buttons and switches that must be activated in the correct order that even a CIA codebreaker would balk at the assignment. So instead of sitting there trying to figure out how you're going to pass this lie off, take that time to grab some pointers from her about what she likes. And while you're at it, work those muscles in your mouth and fingers — a little exercise goes a long way, gentlemen.
